実験手順: To a suspension of 146.6 mg of (S)-3-[(R)-1-(3-methoxyphenyl)ethylamino]pyrrolidine dihydrochloride, 112.5 mg of 1-bromo-2-trifluoromethylbenzene, 22.5 mg of palladium acetate, and 62.3 mg of BINAP (2,2′-bis(diphenylphosphino-1,1′-binaphthyl)) in 5 ml of toluene was added 336 mg of sodium tert-butoxide, and the mixture was stirred at 80° C. for 16 hours. To the reaction mixture was added a saturated sodium bicarbonate solution, the mixture was stirred and then the liquids were separated. The organic layer was dried and concentrated, and the residue was purified by NH silica gel column chromatography (hexane:ethyl acetate-97:3→80:20) to obtain 78.9 mg of (R)-1-(3-methoxyphenyl)ethyl-[(S)-1-(2-trifluoromethylphenyl)pyrrolidin-3-yl]amine. (2) In 10 ml of chloroform was dissolved 78.9 mg of (R)-1-(3-methoxyphenyl)ethyl-[(S)-1-(2-trifluoromethylphenyl)pyrrolidin-3-yl]amine, and 1 ml solution of 4M hydrochloric acid in a dioxane was added to the mixture and the resulting mixture was stirred. The reaction mixture was evaporated, and diethyl ether was added to the residue, and the precipitates were collected by filtration and washed with diethyl ether to obtain 66.7 mg of (R)-1-(3-methoxyphenyl)ethyl-[(S)-1-(2-trifluoromethylphenyl)pyrrolidin-3-yl]amine dihydrochloride (the following Table A1, Example 1.001). the mixture was stirred the liquids were separated The organic layer was dried concentrated the residue was purified by NH silica gel column chromatography (hexane:ethyl acetate-97:3→80:20)
